ALBERT A. BISSELL, OF JOLIET, ILLINOIS, ASSIGNOR OF ONE-HALF TO ED-IVARD R. KNOWLTON, OF SAME PLACE.

ASH-PAN FLOR LOCOMOTIVES.

SPECIFICATION forming part of Letters Patent No. 307,084, dated Qctober28, 1884.

(No model.)

To all whom it may concern.-

Be it known that I, ALBERT A. BrssELL, a citizen of' the United Statesof America, residing at J oliet, in the county of Will and State ofIllinois, have invented certain new and use 2o Referring to thedrawings, G is the grate of the fire-box of a locomotive.

A is the aslrpan sides, formed of sheet-iron or boiler-iron, having acast-iron bottom, B, the two being riveted together by means of theflanges H. The angle-iron strip F furnishes means for securing thedevice to the grate above and for holding in'the apron D by means of heflanges E. The bottom I3 of .the asli' paii is stationary, and isprovided 0 with a series of equidistant cross-slots, I,

designed to be opened and closed by the vibration of the apron D, andfurnishing means for the ashes and cinders to fall through as they arealternately opened and closed by the 5 apron. i

D is the reciprocating apron, designed to be made of cast-iron in theform shown in Fig. 1.- Its cross-bars and ends and also its sides Dslope toward each other, and thereby 40 cause the ashes to more readilyfall through between them when the apron reciprocates. Reciprocatingmotion is given the apron D by means of the arm a, pivoted to it betweenits integral ear-lugs, L, attached at one end, 5 as shown in Fig. 1. Theother end of said arm is keyed to the rock-shaft S, which runs acrossthe pan and journals in its sides. Arm 0 also is keyed to said shaft andhas attached to its outer end the rod 0, which passes up into the cab ofthe engine, where it may be operated by the engineer. Vertical motion ofthe rod 0 will reciprocate the aprons on the top of the slotted bottom Bof the pan A. Each end of the pan is provided with a damper, d and d.Damper (Z is opened 5 and closed by means of its attachment to rod g bymeans of the bell-crank '1, rod 01,, and crank m. Damper d is opened andclosed by means of the rod t, attached to the arm 15, attached to saiddamper. These dampers are for the purpose of regulating the draft upthrough the grate.

The advantage to be derived by reciprocating the aprons instead ofhaving them stationary and reciprocating the bottom of the pan or aslide is that when the slotted bottom is reciprocated under the apronsthe aprons hold up the cinders and ashes so they will not feed downbetween them and out through the slots 1. \Vhen the aprons reciprocate,they move and displace the whole body of ashes and cinders, and causethem to be broken up and feed through readily.

I am aware of the use of an ash-pan for 10- comotives having apronssimilar to these, and 7 5 a slotted bottom under them, in which theslotted bottom is vibrated or reciprocated and the aprons above itstationary. Such construction I do not claim. By this arrange ment theslots P in the bottom are designed so to be closed by the apronswhilethe locomotive travels, to hold the ashes until its destination isreached, when they are dropped through said slots by reciprocating theaprons, as stated, so the ashes and oinders will not be strewed allalong the track. The apron D and slotted bottom Bare both intended to bemade of cast-iron so that their meeting surfaces can be planed up, sothey will work smoothly together. The slots 1 left in the 0 bottomBwould weaken it. For that reason strengthening-ribs Z are used to passunder it for its support. These ribs may be cast in tegral with saidbottom or be separate and bolted thereto by means of bolts.

Having thus described my invention, what ters Patent, is as follows, towit: adapted to operate substantially as and fortho I claim as new, anddesire to secure by Let shaft S, arms a and c, lugs L, and rod 0, all
